Field recording from the top of Hoogh Catherijne, Utrecht

For next Tuesday you will need to make two recordings outside of school. Each recording should be five minutes long and each should be made in different locations. Choose one outside and another somewhere inside. Try your best to find aurally interesting locations.

Also be sure to note the exact location for each recording. You will need to create a Google Map link like this one to York College and include it for each location. This is going to allow me to create a single Sound Map of all your recordings. Hopefully this will prove to be an interesting map to navigate!

Embed your two recordings in a blog post, following the good blogging standards and make sure you include your Google map links!

And as you continue to learn about the typical features of various recorders and microphones, take notes about the following technical details:

Channels
Stereo/mono
1 channel vs. 2 channel recording

File format
Wav/mp3
Sample rate
Bit rate

Gain
Manual vs. Auto
Other gain controls including particular frequency gain controls (lo cut filter at 150Hz for example)
Various limiters/compressors, cut -10dB intervals.
Do gain control settings change with internal vs. external mics

Mic
Directionality (omni, cardiod, hypercardiod, etc)
Tranducer type – dynamic vs. electric condenser
Powered/not powered (on the recorder you may see the option to add +48V, or phantom power, power on/off)
How it’s handled? Hand held, shotgun, lavalier (tie-clip mic, clip on mic), surface mic)

Listen/Look
You are not recording properly if you’re not listening via headphones. Also notice the headphone volume.

But look at the device’s meters. At what level (in a dB description) is your recording at. dB average, low, peak.
